BTW: to make it more easy to discover at make runtime whether the bug has
been fixed in the make version in use, could a proper new entry be added
to .FEATURES?  Maybe 'can-have-lazy-variables'?  (I know, I suck at choosing
names).

Better again: would you consider the possibility of adding a new kind
of variables (let's call them "lazy"), so that a definition like:

    LAZYVAR = val

behaves exactly as:

    LAZYVAR = $(override LAZYVAR := val)$(LAZY)

WDYT?
